In Korea, we call anthum - the weather of books. It's the best weather to read books and rest. So, I want to recommand you the best series, I've ever read. It's not Harry Potter - even though, it's exciting. It's "Percy Jackson and the Olympians". They have five books - The Lightnin' Theif, Sea of Monsters, Titan's Curse, Labyrinth... something and Last Olympian. It's the best myth-fantasy books right now. It has lots of climax and wars - which is really interesting for boys and a bit of romance for girls.
The cycle of a hero just fits to this book's protagonist, Percy. They have a final battle and etc. It's the best book you can read, and I think you are gonna miss it. Read it now!
